Hello, all...
In response from interested parties, I'll post a new topic here rather than hijack another's thread...
The work that I've been doing with Marker has been coming to fruition, and they include replacement / scratch building parts, such as bolsters, coupler shims and some others.
Bolsters:
They are a drop-in replacement for Atlas-style bolsters; which you can see was broken & epoxied in the last picture.
Coupler shims:
The last photo is the "Hybrid" spacer that I've designed to fit both horizontal and vertical lugs on Atlas Master & Trainman cars.
A new spacer will be designed today for Atlas cars that need a thinner (0.080") spacer, and don't have lugs (Like their Steel Reefers; see second picture from top), and will have the mounting holes there for the vertical holes, and counter suck so the Kadee-style coupler box will sit flux against the bottom of the spacer.
I'll post pictures when available.
Thanks,
Mario
